What is the typical land requirement per MWp?

~2.5 acres per MWp for fixed-tilt and ~3 acres per MWp for single-axis tracker systems. We optimise this with terrain-following layout and road-free internal access designs where feasible.

Can you handle NEPRA / AEDB licensing and wheeling for captive IPP?

Yes — our regulatory team manages generation license applications, tariff petitions, generation and metering code compliance, and tri-lateral wheeling agreements for multi-site captive consumers.

What PR (Performance Ratio) should we expect in Pakistan conditions?

Well-designed utility-scale sites in Punjab/Sindh typically achieve 80–84% PR on P95 basis in Year 1, declining ~0.4–0.6% per year with panel degradation. We guarantee PR bands in EPC + O&M contracts.

Do you offer hybrid solar + wind + BESS utility designs?

Absolutely. Pakistan's wind corridor + solar irradiance complementarity is ideal for hybrid utility projects, and RS engineers combined PV-wind-BESS with co-located Substations for optimal wheeling and grid utilisation.
